Relationship between Testicular Volume and Conventional or Nonconventional Sperm Parameters

Abstract

Background. Reduced testicular volume (TV) ( 15 cm3) and B Group, including 38 patients with reduced testicular volume (TV ≤ 12 cm3). All patients underwent serum hormone concentration, conventional and biofunctional (flow cytometry) sperm parameters evaluation. Results. With regard to biofunctional sperm parameters, all values (mitochondrial membrane potential, phosphatidylserine externalization, chromatin compactness, and DNA fragmentation) were strongly negatively correlated with testicular volume (). Conclusions. This study for the first time in the literature states that the biofunctional sperm parameters worsen and with near linear correlation, with decreasing testicular volume.
